When working in a medium sized office setting, you tend to share links with your co-workers, and then forget to show your other friends. This is a demonstration of what a recent study claims we spend 25% of our office time doing (while maintaining or even increasing productivity). Our managers, on the other hand, would call them "distractions".

They placed a linen sheet flat over a volunteer and then rubbed it with a pigment containing traces of acid. A mask was used for the face.

PIGMENT, BLOODSTAINS AND SCORCHES

The pigment was then artificially aged by heating the cloth in an oven and washing it, a process which removed it from the surface but left a fuzzy, half-tone image similar to that on the Shroud. He believes the pigment on the original Shroud faded naturally over the centuries.

They then added blood stains, burn holes, scorches and water stains to achieve the final effect.
